Default Bad Hi Tec servo?

I just got a Tekin 55 t motor and a FX-R ESC for my AX10,also put on a Hi Tec HS-645MG servo ,and it worked for maybe a minnute and all it will do now is buzz.When I first turned it on it turned to thr left .Is it something I did or is it bad?

Yeah those 645mg's have a very weak gear set I wouldn't doubt failure.

when you first turned it on did you have a servo horn installed? I usually set the trim i the middle then, turn the power on without the servo horn on to allow the servo to center itself, then put your wheels straight and install the horn on the servo, then use the trim adjustment to make sure the wheel are straight and the set epa's if you have em. your servo may have tried to center itself but could not because the steering maxxed out first. I doubt it wrecked the gears, but it could have smoked the electronics. I have 4 or 5 645's on various rigs, they are a good budget servo backed by a great warrenty. Take your servo horn off the servo and turn the power on and see if it works............Good luck
